While I do admit I wasn't thinking about the technical aspects of Linking and partying while making this suggestion, the intent is to leave EXP totals per reset as they are (or if anything, a little higher), but letting you do any Guildleves you want. Partying with people outside of your level range should be neither better nor worse than in the current system - it should be the same.
Whether this means that the pool should personal or not, I don't really care.
Do keep in mind that currently the bonus for simply being in a party is small. The pool increase would be too. It's the links/stars/favor that really increase exp gained, and those are what would have the biggest impact on the pool as well. None of these 3 are effected by the different ranks of the party members as far as I know.
